VAC measuring instrument

Transcription

1 Data sheet VAC measuring instrument The service instrument for ventilation and air conditioning systems Point and timed mean value calculation Direct display of the volume flow Automatic allocation of duct cross-section area to measurement site (max. 99 measurement sites) Internal measurement value store (3000 measurement values) PC software for the analysis, archiving and documentation of the measurement values (option) Measurement of up to 6 measurement parameters simultaneously C %RH m/s hpa ppm CO 2 ppm CO This service instrument is s real multi-talent: the has two probe inputs for the connection of a broad range of probes for measurements on ventilation/air conditioning systems. The instrument records flow velocity values in a duct, at a duct outlet or on extraction systems. In addition to this, the allrounder measures or calculates the parameters volume flow, Indoor Air Quality, temperature, relative humidity, dewpoint, absolute humidity, degree of humidity, enthalpy, pressure and CO. At the simple press of a button, the displays the last measurment value measured as well as minimum, maximum and mean values. In addition to this, measurement data can be stored according to measurement site and analyzed on a PC, or documented on site with the Testo fast printer.
